Thanks! Ah, the good 'ol upgrade to PHP 7.3 ... it likes to notify about everything :)

The cause is that the thermal value is loaded as a string (not an integer) and then math is applied to it (so I'm doing math on a string, technically). I'll patch this for you tonight (will make it load the thermal value as a float rather than a string). So you should see those emails stop after your nighly update (or you can force it with a sudo nems-update).

Thanks again for pointing this out.

Did I help you out? Appreciate what I do? Please consider saying thanks:

Yea, not a space issue, and the sd card appears fine and is still working OK.
I did have to run an fsck on the partition, which did fix errors.

I didn't mean to infer your update caused my issue as such, I thought it worth reporting the output on the ever so slight possibility that it was related. I'm comfortable with it being pure coincidence.

If I have another issue, I'll bin the card and use another.
I'll put it down to cosmic rays for now.

Feel free to close this one, as the actual bug has been fixed.
Thanks again.
